Here's where that gets confusing: the one employee of the business who contributed to the SEP is the sole S-Corp owner of the business, and the only employee of the business. So the account is still held by the owner of the business, because the employee and owner are the same person.  So basically you are telling me that I need to tell the business owner if he wants to know how much he put in his SEP later on he has to ask his brokerage?
